The dsPIC33FJ32GS610 families of devices contain extensive Digital Signal Processor (DSP) functionality with a high-performance 16-bit microcontroller (MCU) architecture.
- Up to 40 MIPS operation (at 3.0-3.6V): – Industrial temperature range (-40°C to +85°C) – Extended temperature range (-40°C to +125°C) High-Performance DSC CPU:
- Modified Harvard architecture
- C compiler optimized instruction set
- 16-bit wide data path
- 24-bit wide instructions
- Linear program memory addressing up to 4M instruction words
- Linear data memory addressing up to 64 Kbytes
- 83 base instructions: mostly 1 word/1 cycle
- Two 40-bit accumulators with rounding and saturation options
- Flexible and powerful addressing modes: – Indirect – Modulo – Bit-Reversed
- Software stack
- 16 x 16 fractional/integer multiply operations
- 32/16 and 16/16 divide operations
- Single-cycle multiply and accumulate: – Accumulator write back for DSP operations – Dual data fetch
- Up to ±16-bit shifts for up to 40-bit data Direct Memory Access (DMA):
- 4-channel hardware DMA
- 1 Kbyte dual ported DMA buffer area (DMA RAM) to store data transferred via DMA: – Allows data transfer between RAM and a peripheral while CPU is executing code (no cycle stealing)
- Most peripherals support DMA
